Title: Remotely controlled mechanical actuator
Inventor: LESLIE CHARLES DONALD
IPC: G05G7/10
Filed: 1965-07-09
Abstract: 1,080,828. Cams. CAP-ROC Inc. July 9, 1965, No. 29222/65. Heading F2K. A lever 22 is rocked about a pivot 20, e.g. to initiate operation of a button stitching machine, by a cam 38 on a shaft 36 driven by a motor (32) (Fig. 2, not shown) through reduction gearing 34, under the control of an electrical circuit (Fig. 5, not shown) which controls energization of the motor (32) and of a solenoid 64 which operates a locking lever 54 for the lever 22. Closure of a foot-operated switch (94) energizes the solenoid 64 to pivot the locking lever 54 out of locking engagement with the lever 22, and energizes the motor (32) to rotate the cam 38 from its indexed position, wherein the roller 28 on the lever 22 rests at the foot of the cam rise, to give immediate movement of the lever 22. After initial movement, a lip 44 on the cam 38 releases a holding switch 52 which closes to maintain the motor current when the foot switch (94) is released to de-energize the solenoid 64. Prior to reaching the indexed position again, the cam lip 44 opens the switch 52, the cam and its drive being stopped abruptly in the indexed position as the lever 22 is stopped by the locking lever 54 which is returned by a spring 74 to its locking position. For continuous rocking of the lever 22, the foot switch (94) is held closed contenuously. A spring-loaded stop (182) (Figs. 6-10, not shown) may be provided to prevent rebound of the cam 38 from its indexed position when it is stopped abruptly.

Title: Improvements in and relating to variable reactance devices
IPC: H01P7/02
Filed: 1949-11-16
Abstract: 659,726. High-frequency impedance structures. BRITISH THOMSON-HOUSTON CO:, Ltd. Nov. 16, 1949, No. 29345. Convention date, Nov. 26, 1948.

Title: Improvements relating to direct current transmission systems of the step by step type
IPC: H04L7/10
Filed: 1946-10-02
Abstract: 622,242. Electric synchronous movements. WHALLEY, H., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Oct. 2, 1946, No. 29394. [Class 40 (iii)] Automatic aligning apparatus for a step-bystep electric transmission system comprises cam-operated receiver contacts which in the lining-up position vary the bias of a thermionic valve to operate a relay and disconnect the transmission line, and cam-operated transmitter contacts which in the lining-up position vary the bias of the thermionic valve so as to deenergize the relay and re-connect the transmission line. The receiver shaft 2 of a step-bystep transmission system is synchronously driven by the transmitter 1, but, since such a system has a number of stable positions, the receiver may start out of phase with the transmitter. A cam therefore closes receiver contacts 4 in the aligning position, earthing the suppressor grid of a pentode 9 and so energizing an anode relay 8 which disconnects the receiver drive circuit, stopping the shaft 2 in its aligning position. The relay 8 may, in addition, operate braking means. The transmitter continues to rotate and in its aligning position closes contacts 3 which apply negative bias to the pentode control grid and so de-energize the relay 8 which allows the receiver to rotate again. So long as the receiver and transmitter continue to rotate in correct alignment, the contacts 3 and 4 close simultaneously and their biassing effects cancel out. Fig. 2 (not shown) shows a modification in which the contacts 3, 4 are normally closed.

Title: Improvements in or relating to cartridge-actuated pin or bolt driving tools
IPC: B25C1/12
Filed: 1956-09-26
Abstract: 810,686. Cartridge-actuated pin or bolt driving tools. HOLZ, E. Sept. 26, 1956 [Sept. 29, 1955], No. 29403/56. Class 119 Relates to a cartridge-actuated pin driving tool which is opened and closed for breech loading by a turning movement of the front barrel part 2 relative to the rear part 1 containing the breech block and firing mechanism. According to the invention on closing the breech a nose 45 on the breech block 7 engages an annular groove 46 on the breech end of the barrel 13 to lock the breech block thereto while at the same time a nose 42 on the rear part 1 engages a groove 44 in a support block 35 for the barrel. The pivoted movement of the parts 1, 2 may be about any axis remote from the barrel axis e.g. perpendicular or inclined thereto, but as shown it is about a parallel axis, i.e., the axis of a swivel pin 39 linking the parts 1, 2 a spring-urged locating pin 40 retains the two parts in the firing position. A control ring 9 in the breech mechanism is urged into the position shown by a spring 18 so that normally a ball 26 arranged in a recess in the breech block 7 prevents forward movement of the firing pin 10. On pressing the tool against a wall, the barrel 13, breech block 7 and control ring 9 are moved rearwardly until a flange 9<SP>1</SP> on the ring 9 engages behind the trigger nose 5<SP>1</SP>. On pulling the trigger 5 the control ring 9 is moved rearwardly away from the breech block 7 and the forward chamfered edge of the ring 9 permits the ball 26 to move outwardly and thus release the firing pin 10. The shatter guard comprises a plate 3 secured by screws to the barrel housing and drilled and threaded internally to receive the threaded end of a support ring 14 on which a plate 4 is pivotally arranged The plate 4 has the shape of a sector or a segment of a circle and can, depending on firing conditions such as firing in corners &c., be swung into a lower or upper position. As shown, in the upper position, the plate 4 forms together with plate 3 an annular protective zone about the barrel 13.

Abstract: <PICT:0743306/III/1> Acrylonitrile containing acetaldehyde, hydrogen cyanide and lactonitrile as impurities is refined by feeding the crude acrylonitrile to an intermediate section of a fractionating column, withdrawing lactonitrile (together with high boiling impurities) from the base of the column, withdrawing partially purified acrylonitrile as overhead vapours or as a liquid side stream from the upper part of the column, and immediately introducing this partially purified acrylonitrile (in the liquid phase) into a second fractionating column which is operated under such conditions of temperature and pressure that all the acetaldehyde and hydrogen cyanide in the partially purified acrylonitrile are stripped therefrom and expelled in the vapours leaving the second column while refined acrylonitrile is withdrawn from the base of this second column.  Acrylonitrile containing acetaldehyde (0.5 per cent), HCN (0.01 per cent), lactonitrile (2.5 per cent) and high boilers (3.0 per cent), is fed through line 2 into column 1 (fourteen theoretical plates) which is heated by reboiler 15.  The column is operated at a pressure of 140 mm. Hg absolute.  The temperature at the base is maintained at 50 DEG C., while the overhead temperature is controlled at 30 DEG C.  The overhead vapours, which contain acetaldehyde and HCN, are passed to condenser 5; and part of the condensate is returned to the column through line 6 while the remainder is withdrawn via line 7.  The bottoms withdrawn through line 4 comprise lactonitrile and high boilers.  Liquid acrylonitrile is withdrawn from the sixth plate from the top of column 1, and is passed through line 8 to column 9 (five theoretical plates) which is maintained at a pressure of 140 mm. Hg., and is heated by reboiler 16 to a temperature of 300-32 DEG C.  The overhead vapours from column 9 contain the remainder of the acetaldehyde and HCN; these vapours are condensed in condenser 11, and the condensate is introduced through line 10 into column 1.  Pure acrytonitrile is withdrawn from the base of column 9, either as liquid through line 13, or as vapour through line 14.
